A few doubts here: 1. Which definition of "Refractive Index" are we supposed to write? 2. What's the principle of a machine? 3. Energy conversion in Bulb - Is it Electrical to Light OR Light & Heat? I mean, do we need to mention the degraded form of energy too? |

If we have to draw a diagram for Snell's LAW(only the sin i/sin r, rt? cause only one), should we just draw light travelling from a denser to a rarer medium, mark angles of incidence and refraction and state the law, or is there some other diagram?? |

Ok so if anyone is so kind enough to tell me when to convert kgf to N or even when g= 10m/s^2 is given, when should we convert. and is it necessary to convert to g from kg when solving for the Work done (Kinetic or potential energy.) I know its a silly doubt, but please help me. |
